Viktor Csomor updated HIVE-25925:
---------------------------------
Description:
Instead of calculating the age on the Database side for the
{{oldest_ready_for_cleaning_age_in_sec}} we can calculate it in the
AcidMetricsService. At the moment the {{CQ_COMMIT_TIME}} is not exposed in the
{{ShowCompactResponse}} therefore the calculation happens in the db query.
It has to be assessed whether it worth to expose this field or not?
> Improve the oldest_ready_for_cleaning_age_in_sec compaction metric
